A colonoscopy through stoma is a specialized procedure that involves the examination of the colon via an existing stoma, which is an opening created surgically to allow waste to exit the body. This procedure is particularly relevant for patients who have undergone colostomy or ileostomy surgeries. During this procedure, a colonoscope, which is a flexible tube equipped with a camera and light, is inserted through the stoma and advanced to the area of the colon that may be experiencing stricture or obstruction. The procedure includes the placement of a transendoscopic stent, which is a tube-like device used to keep the passage open, and this process also involves predilation, a technique used to widen the stricture before stent placement. The use of fluoroscopic guidance, which employs real-time imaging, is crucial for accurately navigating the stricture and ensuring the proper placement of the stent. This procedure is essential for alleviating symptoms associated with bowel obstructions and improving the quality of life for patients with colonic strictures.
